I suggest to set the timeout on the session, that's easier (self._session.timeout = 30 or similar)

I agree. I thought about speficying the timeout directly when the session object is created but it's no supported and there's no setter for it. I didn't think about assigning directly to the attribute. I'll do that.

Nevermind, it doesn't work. The session object does not have a timeout attribute at all. The timeout is directly passed to the method.

Uh, ok that seems to have worked previously, but not anymore.
Other solutions:
- A shim on the request: Feature Request: Add timeout to session psf/requests#2011 (comment)
- in intelmq we have our own TimeoutHTTPAdapter https://github.com/certtools/intelmq/blob/develop/intelmq/lib/utils.py#L692-L726

I've noticed that when facing network problems (e.g. Wi-Fi connection dropped) Shodan may hang indefinitely without timing out. The code calling the Shodan library has no control over this and may be left hanging for a response.
According to the
requestsdocumentation requests should have a timeout:These changes define a
REQUESTS_TIMEOUTconstant which defines a connect and read timeout of 30 seconds each. These timeouts are applied to the_request()method of theShodanclass.
